Hyundai Santa Fe: Air conditioning System / A/C Pressure Transducer. Repair procedures
•
|
Before measuring the pressure of the refriferant line, check
whether the refrigerant amount is charged in accordance with
the specified charging amount.
(Refer to Heating, Ventilation, Air Conditioning - "Specifications")
|
|
1. |
Turn the ignition switch OFF.
|
2. |
Install the refrigerant recovery/recycling/charging system.
(Refer to Air Conditioning System - "Repair procedures")
|
3. |
Turn ON the ignition switch, put into operation the air conditioner.
|
4. |
Calculate the reference voltage of the Recovery/Recycle/Recharge machine
high pressure value using the formula below.
Reference voltage (V) = 0.0088 * pressure(psi) + 0.37
|
|
5. |
Measure the sensor output voltage between terminal "1" and "2".

6. |
If the reference voltage value and the sensor output voltage value are
close to each other, the air conditioner pressure transducer is normal.
|
7. |
If 0V is output or the reference voltage value and sensor output voltage
value are not close to each other, replace the air conditioner pressure
transducer.
• |
Check if the output voltage changes when the high pressure
value of the refrigerant line changes.
|
|
|
1. |
Disconnect the negative (-) battery terminal.
|
2. |
Recover the refrigerant with a recovery/charging station.
|
3. |
Disconnect the A/C pressure transducer connector (A).
|
4. |
Remove the A/C pressure transducer (A).
Tightening torque :
10 - 12 N.m (1.02 - 1.22 kgf.m, 7.4 - 8.8 lb-ft)
|
• |
Be careful not to bend the liquid & suction pipe.
|
|
|
5. |
Install in the reverse order of removal.
• |
When installing, replace it with a new O-ring (A).

Description
The A/C Pressure Transducer (APT) converts the pressure value of high pressure
line into voltage value after measuring it...
Description
The evaporator temperature sensor will detect the evaporator core temperature
and interrupt compressor relay power in order to prevent evaporator from freezing
by excessive cooling...
